Two rows and every row are housed in the anchor fluke seat four anchor flukes, and each anchor fluke is externally connected with pressing plate.
Between central tube upper and lower side and the last lower contact sealing ring is arranged.
Between center plunger and the anchor fluke seat sealing ring is arranged, between central tube and the hollow plunger sealing ring is arranged, the hole of passing through for the anchor fluke projected claw is arranged on the pressing plate.
In the anchor fluke seat and between the pressing plate stage clip is arranged.
Between anchor fluke seat and the top connection sealing ring is arranged.
Flowing hole is arranged at the top connection bottom.
Flowing hole is arranged at cover bottom, top, has stage clip to withstand steel ball in the cover of top.
Between valve seat and the top connection axial hole sealing ring is arranged.
Between plunger and the top connection axial hole sealing ring is arranged, between plunger and the valve seat spring is arranged.
Fig. 1 is total figure that analyses and observe of the present utility model, and the right part figure is the top that is connected to left figure among the figure.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
Fig. 1 represents structure of the present utility model, mainly is made up of central tube 28, packing element, anchor fluke 16, valve seat 8 and steel ball 9.The utility model lower end is connected with oil pipe, deep well pump and tail pipe, and the upper end is connected with oil pipe, to constitute the tubing string in the oil well casing.
Central tube lower end screw thread is connected with lower contact 26, and there is sealing ring 27 outer end under the central tube.Outside, central tube bottom is set with between packing element (comprising two short rubber cylinders 25 and a long packing element type 23) and 22, two short rubber cylinders of hollow plunger and between short rubber cylinder and the long packing element type spacer ring 24 is housed.Sealing ring 21 is housed between hollow plunger and the central tube, sealing ring 20 and dog screw 19 are housed between hollow plunger and the anchor fluke seat, when hollow plunger bears when depressing power, long and short packing element is depressed into bulge and holds out against in sleeve pipe (expression on the figure) inwall, so that packing between the utility model and the sleeve pipe is lived, play the effect of packer.
Anchor fluke seat 12 is equipped with in the outside and the top of central tube external hollow plunger, and anchor fluke 16 is housed in the radial hole of anchor fluke seat.In order to add the intensity of strong anchoring, present embodiment is equipped with the two rows anchor fluke, uniform four of every row, and anchor fluke is a cylindrical tube, the anchor fluke outer end has for grappling to be used and extended projected claw outside pressing plate 14.Each anchor fluke outer end is connected with pressing plate 14 by screw 18, and there is stage clip 15 in the hole (expression on the figure) that has the projected claw for anchor fluke to pass through on the pressing plate at the bottom of the anchor fluke tube and between the pressing plate, between anchor fluke cylindrical and the anchor fluke seat sealing ring 17 is arranged.Space 29 is arranged, the usefulness that voltage supply power liquid stream passes through in the anchor fluke seat and between the central tube.When from the pressurised fluid stream of top through the space 29 flow between each anchor fluke cavity the time, anchor fluke is radially protruding together with pressing plate, and make pressing plate hold out against sleeve pipe (expression on the figure) inwall in oil well, the utility model is anchored in the sleeve pipe.The top connection 1 that has been threaded on the anchor fluke seat has sealing ring 13 between anchor fluke seat and the top connection.For being threaded, and there is sealing ring 27 to seal between the upper end of central tube and the top connection.In the top connection lower part wall axial hole is arranged, top cover 11, valve seat 8, cover 5 and plunger 2 are housed in the hole from bottom to top successively, the top cover has the cylindrical shell of flowing hole for the lower end, steel ball 9 is equipped with at the valve port place of the valve seat 8 of set upper side, top, between at the bottom of steel ball and the top sleeve stage clip 10 is arranged, between valve seat and the top connection axial hole sealing ring 7 is arranged.Overlapping 5 cylindricals has step, and flowing hole (on the figure expression) and to overlap the little position of 5 external diameters be the overcurrent chamber has flowing hole 30 radially in the top connection of the corresponding position of overcurrent chamber and top connection 1, and outer end of hole has plug 6 to carry out shutoff.Flow into from top connection top through the flowing hole of flowing hole 30 and cover 5 as pressurised fluid stream, liquid stream is depressed steel ball, and the flow through flowing hole of cover bottom, top of liquid enters space 29, carries out grappling to drive anchor fluke.Overlapping 5 tops has plunger 2, and push rod is arranged at the plunger bottom, below the plunger and between the valve seat end face spring 4 is arranged, between plunger and the top connection hole sealing ring 3 is arranged.
During use,,, press off steel ball and the space of flowing through, make anchor fluke protruding to finish grappling through flowing hole 30 from top connection inner chamber injection pressure liquid stream.Meanwhile, pressurised fluid stream compresses spreading with packing element, to finish packing.When removing grappling and packing, remove in the top connection pressurised fluid stream and from the utility model outside injection pressure liquid flow, 31 enter from entering the mouth, actuation plunger moves down with deblocking; Under stage clip 16 elastic force effects, anchor fluke 15 rebounded to be resetted to disanchor.The pressurised fluid stream that is stored between anchor fluke is discharged through flowing hole 30.
The utility model contrast prior art has following advantage:
In grappling, finish packing; Easy to operate; Structure is simpler.
